HAT-R OUNDING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 477,991, dated June 28, 1892. Application filed October 28, 1891. Serial No. 410,053. (No model.)

1'0 all whom it may concern:-

1 3e it known that I, ABRAHAM T. CLASON, a citizen of the United States, residing at Danbury, in the county of Fairfield, State of Connectlcut, have invented certain new and useful Improvements i n Hat-Rounding Machines, of which the following is a specification, reference being had to the accompanying drawmgs and to the letters of reference marked thereon.

The object of my invention is to cut a hatbody to a predetermined size and round off 1ts edge after the process of pinning out and beforethe hat-body is blocked or curled.

My invention consists of the devices and combinations of devices hereinafter fully set forth in the claims.

In the drawings, Figure 1 is an elevation of a machine embodying my invention. Figs. 2, 3, and 4. are detached details on an enlarged scale. Fig. 5 is a modification.

Similar letters of reference indicate similar parts in the respective figures. A represents the main supporting-frame of the machlne, and B a vertical shaft suitably ournaled therein, to be driven in any ap- The mechanism illustrated to perform this function forms no part of this invention and need not, therefore, be partlcularly described. The shaft B carries at its upper end the cone C, which may be of.

wood, metal, or any other suitable material. Thls cone is provided with a series of circumferential grooves c 0, into either of which the edge of the cutting-disk D is adapted to enter.

E represents a bent arm pivoted ate to the brackets e, which are firmly secured to the main frame. The. upper portion E of this arm is provided with bearings F F to support the rod G, on which revolves the conical pressing-roller G, adapted to bear against the cone C or a hat-body thereon. The bearings F F are adjustable toward or away from the cone 0 by meansof the nuts ff, and the rod G is held in position in its bearings by the collars g g and set-screws g g. The upper end of the conical roller G is enlarged, as shown at G ,'and curves over the top of the cone 0, thereby preventing the hat-body while being operated upon from riding up the cone 0. The lower portion of the conical roller G is composed of a series of removable collar 9 must be capable of adjustment on 1 the rod G and secured thereon by means of a set-screw g? or other equivalent device.

The cutting-disk D is secured to the upper face of a chuck H in any suitable-manner, preferably by means of screws 01 d, which permit of its easy detachment, and the chuck His mounted on a vertical pin Iso as to be capable of revolution thereon, but incapable of vertical movement.

In Figs. 2 and 3 I have shown diiferent ways of connecting the stem and'chuck together, and the special. means employed for this purpose may be varied so long as the cutting-disk is enabled to revo1ve.uniformly in a certain plane. The pin I passes through a horizontal bar J and is secured therein by means of a set-screw i. The bar J .at one end fits into a sleeve K and is adjustable longitudinally therein, it being held .in any desired position by means of a set-screw j. The sleeve K forms the horizontal member of an angle-bar, the other member K being slotted vertically, as shown at it. Through this slot one or more threaded bolts Zpass, the said bolts being firmly secured in the arm E, and nuts Z, adapted to be screwed on said bolts and bear against the member K of the angle. 1

bar, will securely hold the latter in position,

and also permit of its vertical adjustment.

From the foregoing it will be apparent that the cutter-disk D may be vertically adjusted by 'means of the screws and nuts 11', and also I adjusted laterally toward oraway from the cone C by means of the bar J, sliding in the sleeve K. i r

In Figs-1, 2, and 3 I have shown acuttingdisk having a plain cutting-edge, this form being preferred for some classes of goods. WVith other classes of goods I find, however,

that a cutter-disk provided with a series of cutting teeth, preferably lancetshaped, as shown in Fig. 5, in which (Z (Z represent the teeth, can be used to better advantage. These teeth are sharp-pointed and have a cuttingedge on both sides, and also at the angles between the teeth, so that they cut by transfixing the material. They also have a shearing cut by reason of the revolution of the disk in the groove 0.

In order to operate the arm E (which normally has a tendency to lean toward the cone 0) to move it and the conical roller away from the cone, I pivot a lever M to brackets m, secured to the main frame, and pivotally connect one end of the lever to the arm E. Pressure applied to the free end of the lever the cone (1, carrying with it the conical roller G and cutter-disk D, thus enabling the operator to place the hat-bodies upon or remove them from the cone. The cutter D should be arranged to Work as closely to the lower end of the conical roller G as possible, it being desirable that the goods shall be held firmly during the operation of cutting. By removing one or more of the sections 9 from the conical roller G and adjusting the cuttingdisk D to enter the circumferential groove 0 immediately below it hats of dilferent sizes may be cut, the grooves 0 being, of course, graduated for the various sizes. The conical roller G and the cutter-disk D are revolved by frictional contact with the hat-body on the cone 0 when the latter is revolved by means of the shaft B.

I do not limit myself to the exact devices illustrated and described for attaching the Various parts together or securing their adjustment, as other well-known mechanical means may without departing from my invention be employed to accomplish the same results; but,

Having described my invention, I claim 1. The combination, with a revoluble cone i adapted to receive a hat-body and a conical presser-roller supported to bear on the hatbody, of a cutting device supported to cut the edge of the hat-body on the cone and suitable means to give the cutting device lateral and vertical adjustment relative to the cone,

1 substantially as described. I M will cause the arm E to swing away from '1 2. The combination, with a revoluble cone adaptedto receive a hat-body and provided conical presser-roller supported to bear on the hat-body and having a series of removable sections and a cutting device adjustable to either of the grooves on said cone, substantially as described.

In testimony whereof I have hereunto set my hand and seal.
